ARTICLE HIGHLIGHTS
Research background

Cap-assisted endoscopy for removal of esophageal foreign bodies is a new technique.

Research motivation

With any new technique, studies need to be performed to truly evaluate the effectiveness and adverse events.

Research objectives

This meta-analysis examines cap-assisted endoscopy vs conventional endoscopy for removal of esophageal foreign bodies.

Research methods

An extensive literature search was conducted using multiple databases. Studies that compared cap-assisted endoscopy to conventional endoscopy for the removal of esophageal foreign bodies were included. Odds ratio or mean difference was used to analyze outcomes.

Research results

Cap-assisted endoscopy demonstrated higher odds of technical success (P = 0.002) and en bloc removal (P < 0.01) as compared to conventional techniques. Furthermore, cap-assisted endoscopy showed decreased odds of adverse events (P = 0.02) and mean time of foreign body removal (P < 0.01) as compared to conventional techniques.

Research conclusions

Cap-assisted endoscopy should be considered as a potential first-line option for impacted esophageal foreign bodies.

Research perspectives

Endoscopists may utilize cap-assisted endoscopy for removal of esophageal foreign bodies.
